To connect with the network connected to other modules, as shown in the figure below.Ģ) After completing the schematic drawing of the sub-drawing, in the top-level schematic drawing, right-click the corresponding diagram symbol to synchronize the sub-drawing entrance and port, As shown below. Then, draw the schematic diagram in the sub-drawing of the corresponding module, and place the port under the menu). In the top-level schematic, sub-drawings are generated through Sheet Symbol design stepsġ) Only the steps of the top-down design method are introduced here. Select the country of the sub-drawing principle to generate the chart symbolĪfter selection, the inlets and ports of the synchronized sub-drawings will be automatically placed in the top-level schematic drawing."Designator" is the identifier, and the repeat keyword is used for the multi-channel design in the following text "File Name" is the sub-drawing file name. Bottom-up: Generate chart symbols through drawings in the top-level schematic Ĭhoose to generate chart symbols from drawings： From top to bottom: In the top-level schematic diagram, sub-drawings are generated through Sheet Symbol： Here to explain, there are two methods for multi-drawing design hierarchy: The design of multiple drawings is completed by placing a sheet symbol in the top-level schematic, as shown in the figure below. "It is enjoyable to draw schematics in AD", which is stronger than the schematics of Altium and OrCAD? II. Hierarchical schematic or flat schematic Use the hierarchical chart correctly, you will find that ORCAD/PADS/CADENCE is weaker than AD As for the flat design method or the hierarchical design method, which one is better, I don't want to say anything more here, but according to the needs of the project, just use the best method you feel to complete the schematic design. There is no need to learn software for the sake of learning software, it is just a tool In fact, the person who designed AltiumDesigner must know this software very well, so if you learn to use a software, In fact, you can learn how to use the software by carefully reading the software's built-in help files. The point to be explained here is that most of the design methods in this series of tutorials are learned by learning the help files of the software. After looking at the help file that comes with the software, I found a design method that is multi-drawing and multi-channel design. And there are many modular circuits that have to be pasted from the schematics drawn before, which is very troublesome. In this way, it’s okay if the schematic is simple, but if it’s complicated, all the circuit diagrams are on a piece of paper and it looks a bit different.Ĭonvenient and easy to make mistakes. When I first started learning, I used a flat design method when drawing schematics. I have been using Altium Designer for more than a year. Multi-drawing and multi-channel design of hierarchical design I.
